Assist owner appointed Wärtsilä service engineer to vulcanize seals in situ.

Hello again!

Assist owner appointed Wärtsilä service engineer to vulcanize seals in situ.

Does the above sentence mean "Help Wärtsilä service engineer to vulcanize seals in situ".

I have left out "owner appointed" (appointed by the owner) on purpose.

Is there structure similar to "help somebody (to) do something", namely, "assist somebody (to) do something".

The sentence is from a repair specification.

Thank you.

Yes and Yes to both of your questions! You can eliminate the adjective "owner-appointed" (note that it is more clearly an adjective with the hyphen) to arrive at the subject-verb of the sentence, and help is most always a synonym of assist.
